GUARD-HEAD FOR BARRELS.

SPECIFICATION forming part o Letters Patent No, 365,079, dated .Tune 21, 1887. Application filed April 2, 1887. Serial No. 233,302. (No model.)

To @ZZ whom it may concern,.-

Be it known that we, GEORGE H. KNIF'roN and FRANK O. KNrFroN, both citizens ofthe United States, residing atDenver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in GuardHeads for Barrels; and we do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference mark ed thereon, which form a part of this specification.

The object of our invention is to provide a simple, cheap,and durable guard for the heads of barrels and like vessels.

The invention is embodied in the iniproved construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a top view of a guard made in accordance with our invention, a portion being broken out to illustrate the construct-ion more clearly. Fig.

2 is a sectional view oif the head of a barrel with our improved guard therein, the hinged section or cover being raised. Fig. 3 is an edge view looking in the direction of the arrow, Fig. l; and Fig. 4 is a detail view of a modification, to be hereinafter referred to.

Vhere like letters occur in the several tigures they indicate corresponding parts.

The letter A designates the main supporting ring orplate,which is preferably made of sheet metal, and which is split at one point. Upon this ring is secured another ring, B, also of metal, made in two sections, a and b, hinged together, as indicated at c. Each of these sections is provided with suitable slots, q, q, and d, through which pass studs or buttons p p', e e, andfj'f in the ring A. The studs e e, which pass through the slots d in the section (care headed, so that this sectionis not readily separable from the ring A. The studs or buttonsf,f, andf are fastened in the ring, so that they may be turned easily,and their heads are made narrow, so that when they lie in the proper direction the slots in the section b will permit the said section to be placed down against the ring A and the buttons turned to hold it there, as indicated atf in Fig. l. Upon the ends of the ring A are two pins, p and p, which pass through slots q q in the section a. One end of the bar r is pivoted on the pinp, and its other .end is pivoted on a stud, s, of the short arm of a lever, Z, which latter has its fulcrum on the pin p. The lever Zis bent or twisted at its free end to form a convenient ringer-piece, t. The slots in the ring-sections a and b should extend in such a direction that when force is applied to separate the ends of the ring A and expand it the shanks of the pins or buttons will not impinge against the sides forming the slots so as to prevent such expansion. They should have substantially the direction indicated in the drawings. A rod, nl., extending across the upper ring, may serve as the pintle of both hinges, and a suitable wire-netting is stretched between the sides of the sections to prevent the insertion of a hand into the barrel when the guard is in place. The head of the stndf may be made as a ring to receive a padlock, and the section or guard blocked upon the ring or plate A, as shown in Fig. 4. The bar r may have a series of holes, h, to receive thepivotpin, so that the ring A may be expanded more or less, as may be necessary.

Constructed as described in the foregoing, the guard is applied to a barrel-head as fol lows: Let the lever Z be in the position indicated loy full lines, Fig. 1, and the guard be placed in the head of a barrel in the plane of the chine or groove. Then, if the lever be turned to the position indicated by broken lines in said figure, the split ring or plate A will be expanded so as to extend into said groove. Vhen the ring has been thus expanded, the pivots of the bar r and the lever Zshould be in such a line that the tendency of 9o the ring to contract cannot throw the lever into its original position. The lever can, however, be locked in any position that may be necessary by obvious means. It is plain that the upper section, B, (composed in the present instance of two hinged parts, a and 1),) could be made as a solid disk and the device used as a barrel-head.

XVe do not limit ourselves to the precise details of constructions herein shown and de- ICO ' means, substantially as described, for expanding the split ring.

2. -In a barrel-head guard, the combination of a split ring having pins or studs, a ring ar ranged above the first-described ring, having slots, substantially as shown, through which the studs or pins on the first-described` ring project, and means, substantially as described,

for expanding the split ring.

3. In a barrel-head guard, the split ring having pins or studs, a slotted ring. arranged above said split ring, so that the pins on lthe split ring may project through the slotted rlng and permit thesplit ring to be expanded, combined with an expanding dev ice for the split ring,consisting of a bar, r, pivoted on a pin on the split ring, and a lever, Z, lalso pivoted on a pin on the split ring, the said bar and lever being constructed and operating substantially as described. I

In testimony whereof We affix our signatures in presence of two witnesses.
